Citizen SRP-45 programmable scientific pocket calculator from 1991

[Eddie W. Shore]

This calculator looks similar to the Radio Shack EC-4036 I just bought. Thank you for this thread because now I think I know at the [A ->A] and [B ->B] keys are. Looks like store is the second function and recall is the primary function (outside of stats).

I notice that many calculators find it popular to make Statistics mode the second function of the [ON/C], I find that strange. I have a solar scientific calculator (Staples 27952, it has hole punches designed to fit in a three ring binder) with this setup. On the Staples, I can't access the Stat mode when pressing [2ndf] [ON/C], instead the calculator clears.
